How do whales get caught in fishing nets?

Whales can become entangled in fishing nets due to their size and swimming behavior. When they swim through or near nets set for fishing, they may inadvertently get caught, especially in gillnets, which are designed to trap fish by the gills. The entanglement can cause physical injury, restrict their movement, and lead to drowning if they are unable to surface for air. Additionally, the use of floating gear can make it difficult for whales to detect and avoid these nets.
